Harsingar is the dried leaf of Nyctanthes arbor-tristis L., a small Oleaceae tree also called Parijat or Night Jasmine. The leaf is the main traded part, with flowers sold separately for dye and aroma use.

Botanical identity and the parts in trade

The tree carries opposite, rough-surfaced leaves 6 to 12 cm long on quadrangular young branches. The upper leaf surface is distinctly sandpapery to touch, which is the fastest field identification check.

Flowers open at night and drop at dawn, giving the species name arbor-tristis, the sorrowful tree. The corolla is white and the tube is bright orange. Flowers are collected from the ground at first light.

Four parts trade at different values: leaf for herbal use, flower for natural colour and fragrance, seed for extract work, and bark in small volume. They are not interchangeable and must be specified individually.

Where it grows and when it is harvested

The tree is widespread across northern and central India and is common in temple grounds, gardens and village boundaries. Commercial collection centres on Uttar Pradesh, Madhya Pradesh, Bihar, West Bengal, Assam, Maharashtra and the Himalayan foothills.

Leaf is harvested largely through the year, with better quality from mature foliage in the cooler months. Flowering runs roughly August to December, and the flower window is short, which is why flower lots need advance booking.

Processing and quality pitfalls

Leaves are stripped, cleaned of petiole and twig, and shade dried to preserve the green. Sun drying browns the leaf quickly. The rough leaf surface holds dust, so washing before drying matters and shows up as acid-insoluble ash if skipped.

Flowers are dried very gently, since the orange tube pigment degrades with heat and light. Flower lots with faded tubes fetch a much lower value in the natural-colour trade.

What buyers assay

The plant is characterised by iridoid glycosides, principally arbortristosides A, B and C, along with phenylethanoid glycosides, nyctanthoside and flavonoids. The orange flower tube carries the carotenoid nyctanthin, chemically related to crocetin.

There is no widely accepted commercial assay standard for Harsingar leaf, and the Ayurvedic Pharmacopoeia of India does not carry it as a headline monograph the way Haritaki or Ashwagandha are covered. Buyers therefore contract on identity, purity and physical limits rather than on a marker percentage. Where an assay is needed, an HPTLC fingerprint is the practical route.

Forms that trade

AV Biotech supplies Harsingar as dried whole leaf, cut and sifted leaf, milled leaf powder, and dried flowers on seasonal contract. Seed and bark are quoted on enquiry.

Industry applications of Harsingar

Harsingar sits in a smaller, specialist part of the herbal trade. Demand has grown sharply on the back of consumer interest in leaf decoctions, but grade discipline is still weak in the open market.

Ayurvedic and classical manufacturing

Leaf powder and cut leaf feed kwath, kadha, churna and taila preparations. Harsingar appears in traditional joint-comfort and fever-season formulations, often alongside Giloy, Tulsi and Sonth.

Classical units generally want destemmed leaf with visible green retained, since a brown lot suggests poor drying.

Nutraceutical and herbal tea

Cut leaf is used in single-herb and blended immunity teas and in kadha premixes. Tea-cut buyers need low dust and a controlled particle band.

Supplement brands buy 80 mesh powder for capsules and tablets, and a smaller volume of extract for joint-support and seasonal-wellness positioning.

Extraction houses

Extractors work on leaf and seed. Seed carries the arbortristosides at the highest concentration and is the preferred feedstock for research-driven fractions. Leaf extracts are used in general wellness and joint formats.

Natural colour and fragrance

The orange flower tube is a traditional saffron-substitute dye used on silk and cotton in Bengal and Odisha. Perfumery uses the flower for a night-blooming jasmine character, though volumes are small and seasonal.

Cosmetic and personal care

Leaf and flower extracts are used in scalp preparations, hair oils and soothing skin bases. Flower-based colour also appears in natural-cosmetic formulations.

Common product formats

• Kadha and kwath premixes for seasonal wellness
• Single-herb and blended herbal teas
• Capsules and tablets positioned around joint comfort
• Classical Ayurvedic churna, taila and decoction concentrates
• Hair oils and scalp preparations
• Natural textile dye from the orange flower tube
• Perfumery and aroma extracts from fresh flowers

Traditional use and research context

Harsingar has a long record in Ayurveda, Unani and tribal practice across the Indian subcontinent. Classical and folk texts describe the leaf decoction as a bitter tonic used in fever and joint complaints.

Joint comfort positioning

This is the best-documented research area. Traditionally used in Ayurveda for obstinate sciatica and joint stiffness, the leaf has been examined in adjuvant-induced arthritis models and in in vitro anti-rheumatic screening.

Brands commonly formulate it into products positioned around joint comfort and mobility. Human evidence remains limited.

Seasonal fever traditions

Folk practice across India uses the leaf decoction during intermittent fevers. Interest has grown around dengue and chikungunya seasons, and preclinical work has examined haematological parameters including platelet and red-cell counts in animal models.

This area attracts overstated marketing. No regulatory authority has approved Harsingar for any fever or viral condition, and finished-product claims must not imply treatment.

Antioxidant and anti-inflammatory framing

Compounds isolated from the plant have shown inhibition of reactive oxygen species in blood phagocyte assays. Studies suggest anti-inflammatory activity for the iridoid glycoside fraction in laboratory models.

Immunomodulatory research

Arbortristosides from the seed have been studied for immunomodulatory and antileishmanial activity in preclinical work. Reviews describe this as an early-stage evidence base.

Skin and hair traditions

Leaf paste and oil infusions are traditionally applied on the scalp. Formulators use leaf extract in scalp-comfort and dandruff-positioned cosmetic products.

Notes buyers should carry into claims

Evidence for Harsingar is largely preclinical. Buyers building label claims in regulated markets should be conservative, and should note that fever and platelet-related messaging is specifically restricted in India under the Drugs and Magic Remedies Act.

Part specificity also matters. Seed-based research does not substantiate a leaf-powder product.
